O God, you are the tree of life, offering shelter to all the world. Graft us into yourself and nurture our growth, that we may bear your truth and love to those in need, through Jesus Christ, our Savior and Lord. Psalm 92 is the theme today. Luther tells us that the Law can make us recognize our sin, even make us try to act better â but only the love of God in Christ can make us a new person. Even from the tiniest mustard seed, God can make something great.
